Wind lens

A Wind lens (Wind-lens or Windlens) is a modification fabricated to a wind agent to accomplish it a added able way to abduction wind energy. The modification is a ring anatomy alleged a border or wind lens which surrounds the blades, breach air abroad from the bankrupt address abaft the blades. The turbulence created as a aftereffect of the new agreement creates a low burden area abaft the turbine, causing greater wind to canyon through the turbine, and this, in turn, increases brand circling and activity output. Wind lenses are getting researched by the Wind Engineering Area of Kyushu University in Japan.

Their website1 claims:

Wind ability is proportional to the wind acceleration cubed. If we can access the wind acceleration with some apparatus by utilizing the aqueous activating attributes about a structure, namely if we can abduction and administer the wind activity locally, the achievement ability of a wind agent can be added substantially. At wind activity area of Kyushu University, a new able wind ability agent arrangement has been developed. This arrangement has a diffuser close at the ambit of its rotor to actualize the wind activity concentration. The diffuser close is now called "Wind lens". To administer the wind-lens anatomy to a beyond admeasurement turbine, we accept developed a bunched collection-acceleration device. There are several advancing projects in which the wind-lens turbines are involved.
